Built to DIN 1899 specification, this Series 301 bit measures 0.0165 inches in diameter with an overall length of 0.984 inches. The 118-degree faceted point geometry delivers accurate entry with minimal walking on hard and soft metals alike. A web-thinned, tapered web configuration reduces thrust load at the cutting edge, which matters when drilling at this scale. The spiral flute design promotes efficient chip evacuation in shallow-depth holes. Diameter tolerance is held to +0.000 to -0.004 mm, supporting the tight positional accuracy that micro-machining work demands.\u003c\/p\u003e\n\u003cp\u003eThis bit is rated for aluminum as its primary workpiece material, with titanium alloy listed as a secondary application material. The 5xD flute-to-diameter ratio suits short, controlled drilling cycles typical of precision component work. With a maximum drilling depth of 0.093 inches and a straight-cylindrical shank measuring 1.00 mm in diameter, the bit seats securely in standard collet-style micro-drill chucks used on CNC machining centers, drill presses, and precision hand tools. It is sold individually but requires a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for elevated heat resistance and hardness retention in demanding materials\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning to reduce thrust and improve centering accuracy\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish maintains true diameter tolerance of +0.000 to -0.004 mm\u003c\/li\u003e\n  \u003cli\u003eSpiral flute, regular spiral type promotes chip clearance in short-depth micro holes\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 1.00 mm diameter for secure collet or chuck retention\u003c\/li\u003e\n  \u003cli\u003eBuilt to DIN 1899 standard for dimensional consistency across production runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in aluminum and titanium alloy workpieces per material codes K, M, N, P, and S.

Always secure the shank fully in a properly sized collet or drill chuck and verify runout before cutting to avoid bit deflection or breakage at this diameter. Reduce spindle speed and feed rate compared to standard drill bit guidelines when working in titanium alloy. Inspect the cutting edge and point geometry before each use, as micro drill bits at this diameter are susceptible to tip damage from improper storage or handling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0165 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.984 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.093 inches (2.37 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.004 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 301\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 1899\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9003010004200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731139199282,"sku":"9003010004200","price":171.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd111fcd6435413bceaa9705c4c325e0.jpg?v=1788727423","url":"https:\/\/voomisupply.com\/products\/guhring-9003010004200-micro-drill-bit-0-0165-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
